Abstract: Provided herein are monolayer films, and also multilayer films comprising a core, a subskin disposed on the core, and a skin disposed on the subskin. The films may have an Elmendorf tear in MD greater than about 7.0 g/μm, a dart impact greater than about 6.0 g/μm, and a 1% secant modulus greater than about 200 MPa. In multilayer films, the core comprises a first polyethylene blend comprising an ethylene 1-hexene copolymer and a high density polyethylene composition in an amount between about 0 wt. % and about 40 wt. %. Further provided herein are bags and laminates comprising the present films.

Abstract: The present disclosure provides polyolefin compositions and films and method for producing such films. The polyolefin composition contains about 40 wt % to about 95 wt % of a BOCD polyethylene and about 10 wt % to about 60 wt % of a polypropylene, by weight of the polyolefin composition. The polyolefin composition has a 1% secant flexural modulus MD of greater than 250 MPa and a 1% secant flexural modulus TD of greater than 300 MPa, as determined for a layer of the polyolefin composition having a thickness of about 50 μm and a Dart Impact (Method A) of greater than 15 g/μm and an Elmendorf tear MD of greater than 7 g/μm, as determined for a film containing the polyolefin composition and having a thickness of about 90 μm.
